. The object of the invention is the provision" of a novel and improved link 'to beused in the longitudinal side chains of a tire chainj structure for theconnec'tion of the cross or 1 tread chain, in order to afford aconvenient "assemblageof the longitudinal and cross chainsfto prevent the'tanglingthereot when handled or stored, and to prevent the links from opening up or pulling apart hen the "A further object is the formation of the link in such a manner as notto chafe or in- {jurethe 'side Wall of the tire casing, and

'alsof-in' order not to be opened hp or injured by the rubbing ofthe-chains against 'c'urb or other object whenthe Wheel moves link-from a length of Wireor similar stock vvith the terminals ofithe ire forming hooks at one end of the longitudinal portion of end of the longitiidinal portion, for .connecting the link in the longitudinal chain, ,,With. a loop intermediate said ,hooks' and firsti hamed .loop for the engagement of the cross 'o'h'ain.

construction and arrangement of partg-jas hereinafter described and claimed, it being understo'odthat changes can he made within .the scope of What is claimed, ithout departing from the spirit of theinvention.

Aswell known, tire chaindevices, as generally used, consist in longitudinal retaining chains at opposite sides of the tire, andicross Con t o i hel nk iio tioii and. s eye; 1 in or ,transverse'tread chains-connected to the longitudinal chains to' extend acrossthe, tire.

The portion '7 of each link may. also be pressedor bent between thearins of the 1oop, 'as seen in Fig.3. The portion '7 of the improved. link: takes up the longitudinal strain between the eye 9 and'hooks'lO, 11. The-hook 11 contacting with the portion 7 and :hook lOat that 'side opposite to the bend of the loop 8, will-preventthe link from opening up due to strains between the longitudinal and cross chains. 7 Thehook ll beingagainstthe portion? and hooklO will j I prevent the loop 8 from pulling or springing 'awayfrom the portion 7. The improved link is therefore exceedingly strong and willno't pull open even under excessive strains,"and theterminal' portions or hooks ;10 and 11 of the link are made to contact all the inoreg tightly the greater the strains are to which the link is subjected.

{)The improved links may oscillate in the planes thereofwlien the cross chains 15 come I intoandmove out of engagement with the road or pavement and the-cross chains may also shift longitudinally of the tire tread on the loops'*8, to enable the device to creep around the tire, as well'as obtaining a good gripping'action between the'cross chains and the tread; r I r I FigQ L illustrate a :Vmodification, in that the hook 10 at the end of the'portion "I is I bent 1 back'inwardly, reversely to the hook 11 which is'bent back outwardly the same as .the hooks 10 and '11 hereinbefore described. .Th'e-hooks' 10 and 11 are shown to the assembly 'of the link When the hook 10 '1'.
